Other Parts Discussed in Thread: TPS54227, TPS54228

Dear TI

Is there any bode plot data with 68uF Cout or 22uF x 3pcs for TPS54227 or TPS54228? Customer 'd like to know the gain phase.

Conditon of Vin and Vout are depends on your data.

We typically do not publish loop response for DCAP2. It is inherently stable even though phase margin may be less than 45 degrees. Gain margin is not applicable to DCAP2. That said I may have measured the case for Vin = 12 V and Vout = 1.05 V. If I have it, I will contact you directly.
